Title: Methods of identifying compounds that act as agonists or antagonists for proteins involved in signal transduction
Inventor: LERNER MICHAEL R
IPC: G01N33/566
Filed: 1991-07-17
Granted: 2009-09-01
Abstract: A method for identifying a chemical that acts as an agonist for a G-protein coupled cell surface (GPC) receptor. The method comprises introducing to test cells of a pigment cell line capable of dispersing or aggregating their pigment in response to a specific stimulus and expressing an exogenous clone coding for the GPC  receptor, a stimulant that sets an initial state of pigment disposition wherein the pigment is aggregated within the test cells if activation of the exogenous GPC receptor induces pigment dispersion, or introducing a stimulant that sets an initial state of pigment disposition wherein the pigment is dispersed within the test cells if activation of the exogenous GPC receptor induces pigment aggregation; contacting the test cells set in an initial state of pigment disposition with the test chemical; and determining whether the pigment disposition in the test cells treated with the chemical is changed from the initial state of pigment disposition, wherein a change in pigment disposition observed in the test cells expressing the exogenous GPC receptor indicates that the chemical is an agonist for the exogenous GPC receptor.

Title: Atm cell policing method and apparatus
Inventor: TAKASE AKIHIKO
IPC: H04L47/20
Filed: 1993-02-04
Granted: 1998-08-25
Abstract: In an input cell policing method in a network of an asynchronous transfer mode, according to information contained in a header field of each input cell, a group to which the cell belongs is identified.  For each group, there are set a plurality of time frames having a predetermined length and mutually different phases to count the number of input cells in each time frame period.  For each time frame, the count value of input cells is compared with a predetermined threshold value.          An input cell for which the count value exceeds the threshold value in either one of the time frames is assumed to be an excess cell.  The excess cell is discarded or a violation mark is added thereto.

Title: Intraocular refractive lens
Inventor: WORST JAN GERBEN FRANS
IPC: A61F2/16
Filed: 1992-05-19
Granted: 2003-01-07
Abstract: An intraocular lens surgically positioned in the anterior chamber and to be used in addition to the natural lens to correct the refraction. The lens is fixated by iris stromal support, comprising an optical portion of inner concave and outer convex shape and a side support portion which has one or more pairs of pincerlike extensions for holding a portion of iris tissue. The design provides safe clearance away from the vital structures both anteriorly and posteriorly. This technique of stromal iris support per-mits full pupil motility. Lack of any postoperative decentration allows the system to be used for myopia, hyperopia, presbyopia or astigmatism. A non-transparent, light-impermeable ring may be incorporated to prevent glare or edge effects. The lens provides high predictability of the precalculated optical power.

Granted: 2000-06-06
Abstract: The present invention is a method (100) and apparatus (200) for adaptive entropyencoding/decoding of a plurality of quantized transform coefficients in a video/image compression system. For encoding, first, a predetermined number of quantized transform coefficients are received in a predetermined order, giving a generally decreasing average power. Then the quantized transform coefficients are parsed into a plurality of coefficient groups. When the last coefficient group comprises all zero quantized coefficients, it is discarded. The coefficient groups are then converted into a plurality of parameter sets in the predetermined order. A current parameter set is obtained from the parameter sets in the reverse order of the predetermined order. A current entropy encoder is selected adaptively based on the previously selected entropy encoder and the previous parameter set. The current parameter set is encoded by the current entropy encoder to provide entropy encoded information bits.
